关于东部油气富集盆地勘探可持续性的一些思考

我国东部油气富集盆地（如渤海湾和松辽盆地）已进入高难度，高投入和高风险勘探阶段。根据对其油气地质特征和勘探现状的分析，认为油气越富集的地区或构造带中未探明的油气资源量越多的区域，越需要深入研究和勘探，中新生代盆地与下伏沉积具有叠加作用，目前的勘探层位以及下伏层位存在天然气（特别是煤成气）生成和聚集条件，勘探前景好，基础地质和成藏作用研究是当今油气勘探成果的保障。

Considerations on exploration sustainability in east China enriched petroliferous basins

Exploration in the enriched petroliferous basins in the east China (such as Bohai Bay and Songliao basin) has entered the stage with high difficulty, high cost and high risk. According to the analysis of the geological characteristics and the present exploration status, we consider that the more unproven oil-gas reserves exist in the petroliferous areas or structural belts, the more need for thorough study and exploration there are. The Mesozoic-Cenozoic basins are stacked on underlying sedimentation, and the present exploration targets and their underlying horizons own the conditions of natural gas generation and accumulation (especially coal-formed gas) and show a good exploration potential. The study on basic geology and reservoir forming will ensure the current petroleum exploration achievements.
